. 0410 HIS ATTORNEY Patented Mar. 7, 1933 WILLIAM J. SGULLEY, F PALMY'RA, NEW JERSEY APPARATUS FOR- MAKING A BELT SPLICE Application filed IEebruary r This invention relates to apparatus for and method of making a belt splice, and hasfor an object to provide an improved type of splice in an improved manner and by an 0 improved type of apparatus. r a p A further object of the invention is to provide an apparatus embodying means for clamping a belttend and holding it rigidly within a housing, with improved means for producing a slit wholly within the belt end, entirely surrounded by walls of the belt material. 7

A further object of the invention is to pro- '1' 1 vide a device having means for clamping a beltend and holding the same in fixed posi tion, with a knife or lesser width than the width of the belt, positioned to be driven into the end of the belt, but not severing the belt to its margin in any direction, and with further means for forming perforations through the belt at right angles to the cut of the knife.

A further object of the invention is to provide the method of making a belt splice consisting in clamping a belt end into an apparatus for providing a slit into the end thereof, and completing the belt splice by inserting. a dowel into the slit formed by the apparatus, with fastening means inserted through-the belt and the dowel.

A further object of the invention is to provide the method of making abelt splice consisting in clamping the belt ends separately 1 and individually to hold them against movement, driving a knife longitudinally into the ends of the belts so held to provide a slit or socket into the end of the belt and forming perforations through the belt and through 'j the slit so formed, inserting a dowel into the slits of each end, and inserting fastening means through theperforations of the belt ends andthe dowel. V V

o The invention therefore comprises asan apparatus, a body having a clamping device for receiving and clamping the end of the belt and holding. it permanentlyto position, with a knife positioned to be driven into the end-of thebelt for forming a slit therein, a perforating tool to be inserted through the end of the belt transacting the slit so formed,

Like characters of reference indicate corresponding parts throughout the several views. The apparatus which forms the subject matter of the present application comprises a body made up of several sections The base section 10, carries rigidly secured thereto,' the upper sections 11; At the "end, .'a separate section 12 is provided. The section 11 is p'ere manently secured to theibase 10 as by screws 13, while the section 12 'is employed as a clamp, and such clamping is'brough't about by any approved clamping means, as the screws 1 1. i a

View or the knife and Atthe end oppositethe clampingsection 12, asection 15 is secured to the-base in'any 7 approved manner. 'Screws 16 are shown for the purpose, but it is obvious that this connection may be brought about ,in'anymanner as the connection'is permanent. H r a ,The section 15 is drilled to for for the receipt of the shank 18 of the knife and the views therein are as m a passage 6' 19. A head is preferably provided upon the shank 18. I

A lever 20 is provided, fulcrumed at 20. This lever is provided with a bifurcatedend 18 which sets astride the shank 18. When the shank 18 is driven inwardly by impact upon the head 20, thelever 20 will swing against the body 15. After the out has been made, a blow applied to the lever 20 will retract the knife from its cut.

, The base 10 and the upper section 11 are provided with registering perforations 21 and 22 through which a perforating tool 23 is passed.

In operation, and carrying out the method of making the belt splice, the belt ends 24 and 25 are separately and individually inserted into the opening 26 by loosening the clamping member 12. In the specific arrangement shown, this is brought about by loosening the screws 14:. The belt end is inserted into' the device until the end abuts against the end section 15. The clamping member 12 is now clamped tightly upon the beltsection. As shown, the device is arranged for operating upon an elliptical or oval belt. It is understood, of-course, that the shape of the opening 26 in the device will correspond to the shape of'the belt to be operated upon, or conversely V the shape of the belt will be made to correspond to the opening,

and showing this as oval, or elliptical, is no limitation upon the invention. The passage 26 is, however, constricted by the block 14 so that at that position the belt is firmly clamped, while the section nearer the knife 19 not being compressed, will allow the insertion of the knife.

: Theinsertionof the belt into the opening will force the knife '17 within the socket formed in the section 15, or this may be withdrawn into-that position before the belt is inserted. In any case, the knife will occupy the position shown at Figure 4 when the belt has been inserted into contact with the-section 15. r V I The belt being clamped and held rigidly by the block 14 forming the constriction of the passage 26,.theknife 19 is driven into the end of the belt by force applied to the head 20. This may be by pressure or by hammer blows upon the head as found convenient. In any event, it will be noted that the width of the knife 19. is considerably less than the corresponding width of the belt so that the knife, when driven into the belt end, will form'a wall entirely aroundthe slit provided by the knife being so inserted. The knife having been driven in, is withdrawn from the out thus made by a blow applied tothe lever 20 and with the knife so withdrawn, the perforating tool 23 is inserted. first through the one, and then the other of the registering per forations 21 and 22, and through the belt enclosed therein transacting the cut produced by the knife. The edge of marginal Walls of ratus, and bolts, rivets, or the like, indicated at 29, will be inserted through the registering perforations of the-belt ends and the dowel. Preferably, though not necessarily, the innerside of the belt will receive countersunk heads of these fastening members so that the surface of the belt making contact with the pulley will be smooth.

The exterior of' the belt is of less importance, and this mav be made by nuts upon threaded bolts. The threaded bolts and nuts have the advantage that they may be readily displaced when it is necessary to shorten'the V belt. For shortening the belts, of course, it is necessary to "remove only the dowel from one end and to repeat the operation only so far as one end of the belt is concerned.

Of course, the apparatus forv making a belt splice, herein illustrated, may be modified and changed in various ways without departing from the invention herein set forth and hereinafter claimed.
